The legalization of abortion may incite fear that humankind has gained too much control over the natural world. Although such fear is valid on a personal level, the translation of fear into violence unduly endangers the lives of others. Some see irony in the threat of death by individuals who claim to abhor the termination of human lives.
In 1993 a right-to-life activist fatally shot a doctor outside his clinic in Pensacola, Florida after threats by an activist organization. Following this incident, many medical practitioners from similar clinics around the USA resigned in fear for their lives. Others are protecting themselves and their clinics with bulletproof glass and firearms.
